Abstract: Clutch temperature management in a slip control method and arrangement for a drivetrain including a continuously variable transmission is described herein. The drivetrain includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. The temperature data from the clutch is used to determine the usable torque. Accordingly, the clutch prevents the prime mover from stalling.

Abstract: A calibration method for a slip control arrangement of a driveline including a continuously variable transmission is described herein. The driveline includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling. A calibration method to link a valve command value and a torque allowed to pass through the clutch includes preventing the vehicle from moving and increasing the pressure applied in the clutch while noting the torque % value developed by the prime mover.

Abstract: A user input signal management method for a vehicle provided with a prime mover having an output that rotates and an input for a user input signal that controls the rotating speed of the output of the prime mover. The method including the reception of a signal representative of the position of a user input of a vehicle, the reception of data representative of at least one condition of the vehicle, the modification of the received signal representative of the position of the user input as a function of the data received and the supply of the modified signal to the accelerator input of the prime mover.

Abstract: A slip control method and arrangement for a drivetrain including a continuously variable transmission, forward-reverse clutch arrangement and an optional three-speed gearbox is described herein. The forward-reverse clutch arrangement includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling.

Abstract: A drivetrain control and a method for controlling a drivetrain where the actual engine torque of the prime mover is taken into account are described herein. Illustrative embodiments include control systems and methods where the ratio set point of the CVT and/or the rate of the CVT ratio change are modified according to the actual engine torque of the prime mover.
